THE FLASH
CW, 8:00 p.m. ET
SEASON PREMIERE: This Season 2 premiere of The Flash plays with, but doesn’t really explain or yet exploit, what will be the dominant theme this year: the exploration, and cross-pollination, of an alternate universe. Expect characters as you know them to take on different personalities in slightly different settings, as with the dark alternate universes in all those iterations of Star Trek.
